Sightmark Ghost Hunter 4x50 Night Vision Monocular

The Sightmark® Ghost Hunter 4x50 Night Vision Monocular features a lightweight, durable polymer construction, built for endurance, and a 4x magnification that lends itself well to medium-range observation. The automatic shut-off feature turns the unit off when exposed to bright light sources, saving the night vision tube and ensuring years of operation. Equipped with a high-power infrared illuminator, the Ghost Hunter 4x50 Night Vision Monocular delivers a bright, clear image no matter how dark the conditions and a compact body style for easy travel. Its infrared illuminator catches vivid imaging in low-ambient light conditions or total darkness.
